Miniature rose plant named ‘Poulpal053’

ABSTRACT

A new miniature rose plant that has abundant, orange red flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical designation: Rosa hybrid.

Variety denomination: ‘Poulpal053’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety ofminiature rose plant which originated from a controlled crossing betweenthe female seed parent, an unnamed seedling, and the male pollen parent,also an unnamed seedling.

The two parents were crossed during the summer of 2007 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulpal053’, originated as a single seedlingfrom the stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent primarily by flower coloration and growth habit. Thefemale seed parent is 25 cm in growth height, while the claimed plant is30 cm in height. The male pollen parent has apricot colored flowers,while the claimed variety has orange red flowers.

The objective of the hybridization of this rose variety for commercialculture was to create a new and distinct variety with unique qualities,such as:

-   -   1. Uniform and abundant orange red flowers;    -   2. Vigorous and compact growth;    -   3. Year-round flowering under glasshouse conditions;    -   4. Suitability for production from softwood cuttings in pots;    -   5. Durable flowers and foliage which make a variety suitable for        distribution in the floral industry.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulpal053’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization and conducted evaluations onthe resulting seedlings in a controlled environment in Fredensborg,Denmark. ‘Poulpal053’ was selected by the inventor as a single plantfrom the progeny of the hybridization in 2007.

Asexual reproduction of ‘Poulpal053’ by cuttings was first done byMogens N. Olesen in the nursery in Fredensborg, Denmark in 2008. Thisinitial and other subsequent propagations conducted in controlledenvironments have demonstrated that the characteristics of ‘Poulpal053’are true to type and are transmitted from one generation to the next.
